Filed: 1995-07-11
Abstract: PROBLEM TO BE SOLVED: To simply execute inspection of electrode connection with a small-sized circuit by providing a voltage supplying section, a connection controlling section, a resistance circuit and a testing circuit. SOLUTION: When inspection of short circuit between an electrode T1 and a ground electrode GND is executed, a signal for a test mode is inputted to the electrode T1 and an output of an inner circuit 3 is not outputted. A control signal of a connection control section 6 is inputted to the electrode T2 so that a voltage supplying section 5 and an electrode T5 are connected to each other. A signal that allows the output of the supplying section 5 to be in H state is inputted to an electrode T3 . In this condition, the voltage of an output section T4 of a voltage detection section 7 is detected. When the voltage of the electrode T4 is in H state, it is judged that there is no short circuit between the electrode T5 and the ground point GND. When the voltage of the electrode T4 is in L state, it is judged that there is a short circuit between the electrode T5 and the ground point GND. Thus, it is possible to execute the connection inspection of the electrode in a simple circuit structure. It is therefore possible to reduce rate of occupation of a testing circuit in an integrated circuit device.

Abstract: PURPOSE:To cool efficiency a heat source in a laser oscillator device by a method wherein at least a part of a heat source, for example, a heat exchanger is cooled by the use of the refrigerant of a chilling unit. CONSTITUTION:A refrigerant piping 17 of a chilling unit 10 is disposed to extend through heat exchanger 5 and 6 of a laser oscillator 1 and a refrigerant of the chilling unit 10 is made to flow through the heat exchanger 5 and 6, where the laser gas is cooled by the refrigerant. In this case, the refrigerant piping 17 is connected with the heat exchanger 5 and 6 after it penetrates through a condenser 11, wherefore the refrigerant, which is in such a state as it is ready to vapor at once, is introduced into the heat exchangers 5 and 6. The liquid refrigerant is vaporized by the laser gas of high temperature which flows into the heat exchangers 5 and 6, when the coolant absorbs heat from the laser gas. Therefore, the laser gas can be kept at low temperature, so that a laser oscillation with a high output power can be obtained.
